Though formal hostilities with the PRC ended by the early 1980s, Kinmen is still very much a front line area. Visitors are strongly advised not to wander off paved roads when exploring the island due to the possibility of running across old unmarked minefields. It is also advisible to avoid traveling to certain sensitive areas after dark, such as coastal areas or areas near military installations. Visitors should also obey all orders given by military personnel and avoid entering or photographing sensitive areas.
